Detecting scour and liquefaction using OBS sensors [PDF]

, 2016
This work examined the performance of Optical Back-Scatter (OBS) sensors for detecting sediment movement around a model subsea structure. Three types of tests were conducted using a circular cylinder model equipped with 16 OBS sensors.

Simultaneous Effect of Collar and Roughness on Reducing and Controlling the Local Scour around Bridge Abutment

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2017
Investigation of local scour around hydraulic structures particularly bridges is of crucial importance in river engineering. Bridge destruction mostly occurs as a result of scour phenomenon around piers and abutments, not because of structural weaknesses.

Scour Development in Square Pile Groups: Effects of Pile Number and Spacing

Civil Engineering Dimension
Local scour around pile group foundations poses a significant risk to hydraulic and coastal structures, particularly when multiple piles interact with complex flow patterns. This study presents a numerical investigation of local scour around pile groups

Investigating the effect of curved shape of bridge abutment provided with collar on local scour, experimentally and numerically

Ain Shams Engineering Journal, 2015
Scour around bridge supports such as abutments can result in structural collapse and loss of life and property, so there is a need to control and minimize the local scour depth.

Experimental study on local scour around large-diameter submerged cylinders under combined waves and current action

Shui kexue jinzhan, 2019
The characteristics of local scour around large-diameter submerged cylinders are quite different from the non-submerged ones under combined wave and current conditions. Local scour model tests are carried out in a wave-current flume. A submerged cylinder

Wave–Current Force Characteristics of Monopile Foundations on Scoured Seabeds

Journal of Marine Science and Engineering
Local scour around offshore wind turbine foundations is a common engineering challenge. It changes the hydrodynamic loads and affects the foundation’s load-bearing capacity.

SIMULATION OF SCOURING AROUND A VERTICAL CYLINDER DUE TO TSUNAMI [PDF]

Science of Tsunami Hazards, 2017
* Corresponding author radianta@ugm.ac.id ABSTRACT Local scour due to tsunami is damaging especially on shallow foundation. Although relatively in a short duration, tsunami attack may scour material around buildings that led to destruction. A number of

Scour effects on p-y curves for shallowly embedded piles in sand

, 2016
Soil scour around a shallowly embedded pile can significantly compromise its lateral response, reducing both stiffness and capacity. Estimation of the lateral pile response must take into account both the scour-hole geometry and the overconsolidation ...
